Definitions

  • This invention relates to a dirt separator for cards having a cylinder and fixedly mounted carding segments cooperating therewith, comprising a knife blade of which the blade edge is arranged against the direction of rotation of the cylinder at a narrow interval from its clothing adjoining a carding segment.
  • the object of the present invention is to provide a dirt separator which enables the intensity of cleaning and the type of fibres separated out to be adjusted and which has a wider scope of application, particularly in the carding of cotton.
  • this object is achieved in that the knife blade is provided with an adjustment for adjusting the interval between the knife blade and the clothing of the cylinder, and in that the knife blade is preceded in the direction of rotation by a collecting rail which has a substantially flat base surface running parallel to the surface of the cylinder.
  • the interval between the base surface and the cylinder is preferably adjustable. In this way, it is possible to adjust the spectrum of the impurities and short fibres separated out.
  • the clearance between the collecting rail and the edge of the knife blade is also adjustable. In extreme cases, the clearance can be adjusted to zero so that no separation of dirt occurs.
  • the dirt separator is arranged between two carding segments, the knife blade and the associated adjustment being fixed to one of these carding segments and the collecting rail to the adjacent carding segment. This construction eliminates the need for additional holders for the components of the dirt separator.
  • the empty space formed between the knife blade and the collecting rail may be closed by a cover.
  • the empty space thus closed may be connected to an extractor so that blocking of the dirt separator is avoided.
  • the collecting rail preferably has a surface which adjoins the base surface and which faces the knife blade. That part of the surface which adjoins the base surface may run parallel to the plane of movement of the knife blade. In this way, the clearance between the collecting rail and the knife blade is not changed during adjustment of the knife blade.
  • FIG. 1 is a cross-section through the region between two carding segments of a card with a dirt separator arranged in this region.
  • FIG. 2 is a section through a cylinder and three carding segments co-operating therewith.
  • the dirt separator shown in the drawings comprises a knife blade 1 which has a substantially boot-shaped cross-section and extends over the entire width of a card.
  • the knife blade has a shank 2 into which several screwthreaded holes 3 are cut.
  • the base region 4 of the knife blade 1 has a substantially flat base surface 5 which on one side forms a blade edge 6.
  • the blade edge 6 is formed by a blade leaf 7 which is fixed to the base region 4.
  • the knife blade sits in a holding plate 8 which is screwed to one end 9 of a flat card 10, which forms a carding element, by means of countersunk screws 11 screwed into threaded holes 12 through bores in the holding plate 8.
  • the holding plate 8 comprises a U-shaped recess 13 which extends over its entire width and of which the dimensions are such that it is able to receive the shank of the knife blade 1 with a sliding fit.
  • the holding plate is formed with bores 14 in alignment with the threaded holes 3. Adjusting screws 15 are inserted through these bores 14, their heads resting on a shoulder 16 of the holding plate 8.
  • shank comprises bores for clamping screws 17 of which the function is to fix the knife blade in position relative to the holding plate 8 once it has been adjusted.
  • the dirt separator further comprises a collecting rail or trough 18 which has an L-shaped cross-section and which extends over the entire width of the card.
  • the collecting rail 18 comprises a substantially flat base surface 19 which is shaped in such a way that, in the installed position of the collecting rail, it runs parallel to the surface of the cylinder.
  • That edge 20 of the collecting rail 18 which faces the knife blade 1 may be arranged at a distance from the blade edge 6 of the knife blade 1.
  • the collecting rail is provided with an adjusting and fixing mechanism identical with that of the knife blade 1.
  • the collecting rail is held by the same holding plate 8 as the knife blade so that the construction of these components is not described again in the following.
  • the surfaces of the two holding plates 8, on which the knife blade 1 and the collecting rail 18, respectively, are displaceably arranged are arranged at an angle to one another. Accordingly, by adjusting the adjusting screws 15, it is possible to adjust not only the distance of these parts from the cylinder, but also the interval between the edge 20 and the blade edge 6.
  • a curved surface 21 adjoins the edge 20 of the collecting rail 18. If that part of this curved surface which immediately adjoins the edge 6 is shaped in such a way that it runs substantially parallel to the plane of movement of the knife blade 1, it is possible by adjusting the knife blade 1 to alter only the distance between the base surface thereof and the cylinder, but not the clearance between the knife blade 1 and the collecting rail 18.
  • Dirt separators of the type in question may be arranged between all the carding segments of a card and, by appropriate adjustment thereof, it is possible to obtain an optimal separation of impurities, fine dust and fibres.
  • the interval between the knife blade and the cylinder determines the intensity of separation. With a very narrow interval, very fine dust particles (microdust) are separated out along with husk fragments and short fibres. With a wider interval between the knife blade and the cylinder, less microdust is removed.
  • the adjustment range should be between 0.1 and 2.5 mm.
  • the position of the collecting rail determines the amount of impurities and short fibres separated in dependence upon the degree of soiling and the staple length of the fibres.
  • the collecting rail 18 and the knife blade 1 may also be adjusted in such a way that the blade edge 6 touches the collecting rail 18. In this position, there is no separation of dirt or short fibres. This setting is necessary for example for the processing of manmade fibres.
  • the collecting rail 18 may be adjusted in such a way that the interval between the base surface 19 and the cylinder measures up to 15 mm.
  • the empty space between the collecting rail 18, the knife blade 1 and the cover 22 is connected to an extractor so that the particles separated out do not block the dirt separator.
